vsocklib_x64.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like vsocklib_x64.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like MpSigStub.exe - to follow. These files were created so that multiple programs (eg. VMWare Workstation Player) could share the same vsocklib_x64.dll file, saving valuable memory allocation, therefore making your computer run more efficiently.
Unfortunately, what makes DLL files so convenient and efficient, also makes them extremely vulnerable to problems. If something happens to a shared DLL file, either it goes missing or gets corrupted in some way, it can generate a "runtime" error message. Runtime is pretty self-explanatory; it means that these errors are triggered when vsocklib_x64.dll is attempted to be loaded either when VMWare Workstation Player is starting up, or in some cases already running. Some of the most common vsocklib_x64.dll errors include:
- Access Violation at address - vsocklib_x64.dll.
- vsocklib_x64.dll could not be found.
- Cannot find C:\Program Files\Common Files\VMware\Drivers\vmci\sockets\Win8\vsocklib_x64.dll.
- Cannot register vsocklib_x64.dll.
- Cannot start VMWare Workstation Player. A required component is missing: vsocklib_x64.dll. Please install VMWare Workstation Player again.
- Failed to load vsocklib_x64.dll.
- The application has failed to start because vsocklib_x64.dll was not found.
- The file vsocklib_x64.dll is missing or corrupt.
- This application failed to start because vsocklib_x64.dll was not found. Re-installing the application may fix this problem.
Your vsocklib_x64.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with VMWare Workstation Player), or deleted by a malware infection. Furthermore, vsocklib_x64.dll file corruption could be caused from a power outage when loading VMWare Workstation Player, system crash while loading vsocklib_x64.dll, bad sectors on your storage media (usually your primary hard drive), or quite commonly, a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.
